Abstract: A novel ADRC control structure which employs only three first-order ADRCs is

presented for the speed control of induction motor drives, moreover, compared with the existing

ADRC based speed control structures there is no need to estimate the rotor flux. As a result, the

runtime of the proposed ADRC control algorithm is shorter than ever and the implementation of

it on DSPs is easier than ever. The simulation results show that the proposed control scheme still

can overcome the side-effects of internal disturbance and external disturbance, such as the load

disturbances, the motor's parameter variations and the modeling error etc. as good as other

robust control schemes which employ higher order ADRCs. Furthermore, a TMS320F2812 DSP

based prototype using the proposed control scheme was developed. The experimental results

show that the robustness of the proposed ADRC system are obviously better than the

conventional PI system when various disturbances occur, and the scheme is feasible and effective.
